SPECIFICATION forming part of Letters Patent No. 756,926, dated April 12, 1904. Application nea Damm 23,1903. stanno. 186,347. (Numtel.)

, county of New York and State of New York,

have in vented certain new and useful Innorovements in Wall-F acin g for Dampproofing; and I do hereby declare the following to be a full, clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same.

The invention which forms the subject of this patent is directed to the production of a dampproofing film for the walls of buildings and like structures composed of cheese-cloth or similar light cloth iianked on both sides by a layer or coating ofwaterproof paint or composition, one of which layers is applied to the wall to be protected and seryes as a wet backing having an adhesive function upon which the cheese-cloth or similar light cloth is mounted by a smoothing pressure, the other layer applied to theV other side of the cheese-cloth as a finished facing or for forming the mounting forl a plaster facing, whereby to protect interior surface decorations or wall paper from discolorations and the room from dampness.

`In the accompanying drawings, Figure 1 illustrates my new dampproofing film as a facing applied to a building-wall which is shown in vertical section. Fig. 2 shows in vertical section the dampproofing lfilm as it would be produced in constructing it-upon the wall and as being formed of cheese-cloth flanked on both sides by layers or coatings of waterproof paint or composition. The thickness of the waterproof coating is shown exaggerated.

The permeability of exposed walls and their mortar joints render them liable to dampness and the consequent discoloration of their in terior surfaces and unhealthful to the occupants of the house, and to prevent this I provide for facing the wall with a film composed of one or more layers of cheese-cloth or similarv light cloth l, fianked on both sides by a layer or coating of waterproof paint or composition 2 2, one layer being applied to the rough'l'surface of the wall 3 as a mounting for quires no fastening other than that made by the adhesiveness ofthe coating upon the wall to the wet paint, on which it adheres perfectly., and is so light that under a smoothing pressure in applying it all the inequalities in the rough brick surface will be filled, and the cloth will thereby form a durabie bond for the plaster wall, and this, so far as I know and can find, is a new conception in the-art of dampn proofing exposed walls either inside or outside, because for such purpose it is quite dit'n ferent from the use of tarepaper, for the rea son that such paper would not hold on a coat ing of waterproof paint or composition and the plaster would not hold on such paper, nor would such paper embody the impervious character of the paint and cloth fiber composing the film. Moreover, there is no absorbing function in the cotton film other than from the coating, which renders it impervious to moisture. rIhe cloth is mounted byv pressure in sheets upon the waterproof coating and remains intact, even if the wall settles or cracks or the joints open, and may be applied to any construction of' plastered walls.

The dampproofing cotton film can be applied to the plastic facing of walls to prevent the chipping or breaking and gives a smooth surface that will shed water. For outside Walls a second layer of cheese-cloth may be applied, each layer mounted upon an adhesive coating and the outer surface of the cloth film finished by waterproofing. The dampproofing cotton film may also be applied to iron structures, such as bridges, in the same way to prevent rusting and corrosion and to save expense of painting, for the @iieeS--cioti can ba Smooth@ presse upon ai! the busiy proof-mated and than inisiaaci with a l. oi fii'ippi'ozig mataii suiiacas method iiei'eii described., wiiiaii 5011. 1. providing' the with a layer of adhas' fe Waterproof @imposition appyiig Cha-esecloth toA such 3sat-ing uxder pressuie and inforcing the ciiefasemioth with a ii- 'coating of adhesive Waterpiooi compcsitien.
